Interactive 3D data visualization plays a key role in HEP experiments, as it is used in many tasks at different levels of the data chain. Outside HEP, for interactive 3D graphics, the game industry makes heavy use of so-called “game engines”, modern software frameworks offering an extensive set of powerful graphics tools and cross-platform deployment. Recently, a very strong support for Virtual Reality (VR) technology has been added to such engines. In this talk we explore the usage of game engines and VR for HEP data visualization, discussing the needs, the challenges and the issues of using such technologies. We will also make use of ATLASrift, a VR application developed by the ATLAS experiment, to discuss the lessons learned while developing it using the game engine Unreal Engine, and the feedback on the use of Virtual Reality we got from users while using it at many demonstrations and public events.

Interactive 3D

Background: Virtual Reality (VR) was defined as a collection of technological devices: “a computer capable of interactive 3D visualization, a head-mounted display and data gloves equipped with one or more position trackers”. Today, lots of scientists define VR as a simulation of the real world based on computer graphics, a three dimensional world in which communities of real people interact, create content, items and services, producing real economic value through e-Commerce.Objective: To report the results of a systematic review of articles and reviews published about the theme: “Virtual Reality in Medicine”.Methods: We used the search query string: “Virtual Reality”, “Metaverse”, “Second Life”, “Virtual World”, “Virtual Life” in order to find out how many articles were written about these themes. For the “Meta-review” we used only “Virtual Reality” AND “Review”. We searched the following databases: Psycinfo, Journal of Medical Internet Research, Isiknowledge till September 2011 and Pubmed till February 2012. We included any source published in either print format or on the Internet, available in all languages, and containing texts that define or attempt to define VR in explicit terms.Results: We retrieved 3,443 articles on Pubmed in 2012 and 8,237 on Isiknowledge in 2011. This large number of articles covered a wide range of themes, but showed no clear consensus about VR. We identified 4 general uses of VR in Medicine, and searched for the existing reviews about them. We found 364 reviews in 2011, although only 197 were pertinent to our aims: 1. Communication Interface (11 Reviews); 2. Medical Education (49 reviews); 3. Surgical Simulation (49 Reviews) and 4. Psychotherapy (88 Reviews).Conclusion: We found a large number of articles, but no clear consensus about the meaning of the term VR in Medicine. We found numerous articles published on these topics and many of them have been reviewed. We decided to group these reviews in 4 areas in order to provide a systematic overview of the subject matter, and to enable those interested to learn more about these particular topics.

Augmented reality (AR) has experienced a breakthrough in many areas of application thanks to cheaper hardware and a strong industry commitment. In the field of management of urban facilities, this technology allows virtual access and interaction with hidden underground elements. This paper presents a new approach to enable AR in mobile devices such as Google Tango, which has specific capabilities to be used outdoors. The first objective is to provide full functionality in the life-cycle management of subsoil infrastructures through this technology. This implies not only visualization, interaction, and free navigation, but also editing, deleting, and inserting elements ubiquitously. For this, a topological data model for three-dimensional (3D) data has been designed. Another important contribution of the paper is getting exact location and orientation performed in only a few minutes, using no additional markers or hardware. This accuracy in the initial positioning, together with the device sensing, avoids the usual errors during the navigation process in AR. Similar functionality has also been implemented in a nonubiquitous way to be supported by any other device through virtual reality (VR). The tests have been performed using real data of the city of Jaén (Spain).

Virtual Structures

The recent and rapid developments of immersive, interactive 3D environments have been critical in advancing interfaces for entertainment, design, and education. For cardiovascular research, our laboratory and others have been able to use such software tools for the construction of heart models from DICOM files. These models can then be printed in hard or soft plastic from a 3D printer. In general, such models are considered useful for surgical planning and education; these modalities are being applied as critical tools in the field of cardiovascular research. Recently, the development of virtual reality (VR) has introduced a new modality for exploring 3D virtual structures with high resolution, high flexibility, and fast turn-around times. Until recently, the adoption of these technologies has been hindered by the high costs of VR goggles and the complexities in their setup. New developments in phone software and hardware, however, have alleviated some of these difficulties by allowing smartphone screens, graphics units, and gyroscopes to provide the necessary technologies for VR. In this way, phones can be placed inside a headset holder and used freely, without being connected to the computer. Here we explore the utility of using this VR setup in the context of internal heart anatomy visualization.

In this usability evaluation of the Fountain of the Lions software application aimed to be used by museum visitors, the software is analysed using three established usability research methods: personas, a cognitive walkthrough (task analysis) with three participants, and an individual heuristic evaluation. Areas in which the software succeeds and areas which could use improvement are discussed based on the results of these analyses, including use of the methods.
